According to a story in the Malay Mail a car wash in Sunway Mentari, a Malaysian city about ten miles southwest of Kuala Lumpur, had a customer loyalty program even better than double miles.

The car wash had worked out a deal with a nearby massage parlor to offer a unique bonus for those who kept their cars immaculate. To qualify, a customer had to accumulate nine car washes within a certain period. With the tenth wash, the customer was given a free session with a prostitute.

Customers who joined the program were given a loyalty card to be marked with each visit. Of course, impatient customers could pay $42-$59 and not have to wait for all the car washes.

The three-month-old program ended last week with a police raid on the massage parlor.

Police arrested nine Vietnamese women, believed to be prostitutes, aged between 18 and 28.

Assistant Police Superintendent Emmi Shah Fadhil said officers discovered the deal after finding several car wash loyalty cards in the possession of five customers who were caught in flagrante delicto with the prostitutes.

“It was supposed to be just another routine operation,” he said. Emmi Shah said the team later found out that customers who sent their cars to the nearby car wash will be given a loyalty card each.

“When we raided the premises, the women panicked. Some even tried to hide in the storeroom. Four men, believed to be the operators and caretakers, were also detained,” he said.

Emmi Shah said besides the loyalty cards, the team also found several condoms stashed inside a microwave.

Police said the women were found to have violated their social visas and had been working without permits. They were taken to Petaling Jaya police headquarters for further investigation.

While getting a session with a prostitute is newsworthy, sex and suds aren’t exactly unheard of in Malaysia. The first topless car wash opened as a marketing gimmick in Singapore in 2009.
